What are the values for X-ray satisfy the equation

X^2 - 5(x) - 14 = 0

A. -2 and 9
B. -2 and -9
C. 2
D. 2 and -7
E. -2 and 7

Answers

Answer 1

Answer:

It's D

Step-by-step explanation:

you just look at the end it's says -14. u have to see what numbers should multiply in order to get negative 14, you can use -2 and 7, or -7 and 2, but you have to see what numbers from the -14 will add up -5 because u have five in there, therfore -7+2 equals -5.* This only happens if you have 1 behind the x^2.

Which are necessary conditions to apply the SAS Triangle Congruence Theorem? Select all that apply

Answers

Answer:

A.) Two sides and the included angle of a triangle are congruent to the CP of another triangle

Step-by-step explanation:

So, SAS. The Side-Angle-Side congruence postulate.

To have SAS congruence, 2 adjacent sides of a triangle need to be congruent to another triangle's adjacent sides, AND the angles between (re: included angles) them need to be congruent as well.

The answer most similar to that would be A!

A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?

Answers

Answer:

Right, I am an idiot so i might be wrong

Step-by-step explanation:

Every triangle has three angles which sum to 180 degrees.

There are three types of triangles based on the measures of its angles.

Right Triangle - Has one 90 degree angle

Acute Triangle - All angles less than 90 degrees

Obtuse Triangle - One angle greater than 90 degrees

In this example we are given 2 angles and must find the measure of the 3rd.

a + 56 + 34 = 180

a + 90 = 180

a = 90

Therefore, it is a Right Triangle.

Answers

Answer:

∠P = 21

Step-by-step explanation:

angle P is an inscribed angle and arc RQ is the arc it intercepts

The measure of an inscribed angle is equal to half the measure of the arc it intercepts.

Hence, ∠P = [tex]\frac{1}{2}[/tex] ( arc RQ )

So if arc RQ = 42°

Then ∠P = 42/2

42 / 2 = 21

Hence, ∠P = 21°

Round your answer to the nearest whole number.

Answers

Answer:

The radius of the cylinder is approximately 28 feet.

Step-by-step explanation:

A jar contains 5 blue marbles, 1 yellow marble, and 4 green marbles. What is the probability of randomly choosing a yellow marble, replacing it , and then choosing a yellow marble again

Answers

Answer:

1/100

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

the probability = (number of yellow marbles / total number of marbles) x (number of yellow marbles / total number of marbles)

total number of marbles = 1 + 5 + 4 = 10

(1/10) x (1 / 10) = 1 /100
